Figure 9
Comparison of four theoretical models, using the constant Q cut (width of 0.067 Å-1) for Q = 4.6 Å-1 from Fig. 8[link], with experimental data for aluminium at 10 K obtained on the MARI spectrometer, ISIS (grey line). (a) The original LJ 12-6 model, (b) the LJ 12-6 model fitted from MARI experimental data, (c) the original Mei-Davenport model and (d) the Mei-Davenport model fitted from MARI experimental data. The horizontal axes are energy transfer and vibrational frequency (meV and cm-1, respectively) and the vertical axis is S'coh(Q, [omega]).  [article HTML]
